Description
Pouring spout NS 45/40 for flasks and bottles is a laboratory accessory for guided dispensing from glassware that uses a matching standard ground joint. The NS 45/40 joint size is intended for flasks and bottles prepared for this cone, helping operators pour solvents, reagents, and process liquids with improved control and fewer drips around the neck. In daily laboratory practice it supports cleaner emptying and more directed transfer than free pouring from an open vessel mouth. Delivered as a single piece, the spout is aimed at routine handling of jointed flasks and bottles in chemical, analytical, and life-science settings where NS geometry is already standardised. This pouring spout from manufacturer Starke forms part of the pouring-spout range used together with ordinary laboratory glassware. It fits teaching labs, research teams, and production-support environments that work with NS joints and need a straightforward pour accessory. Select the NS 45/40 model when your flasks and bottles are specified for that joint size so seating and pour performance remain consistent across the glassware set in use.

Questions about Spout NS 45/40 for flasks and bottles
What is this article?
Spout NS 45/40 for flasks and bottles is the article on this page. Luminix Health distributes Starke for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
